Greetings to the List - I am scratching my head on this. Lately I've been using my new hearing aid interface as a headphone accessory for my K-3. It is a small box (Phonak brand) that plugs into the K-3 headphone jack, and transmits the audio to my hearing aids via bluetooth. Works great - I enjoy listening to the bands, direct to my ears, without bothering the household, and avoiding some local noise interference.
BUT - when I send CW, the sidetone is absent (and denies me the ability to listen to my transmission). This makes no sense. The sidetone is very present when I use regular passive headphones, or the K-3 speaker, with no adjustments to other settings. As soon as I plug the Phonak in, the sidetone is gone. All other receiver audio is coming through just fine. The problem occurs whether I am using straightkey or paddle. I'm assuming there's some kind of active voltage coming from the Phonak into the headphone jack but why does it only affect the sidetone? Reaching for the schematic...
